WARNING: This page is about a different car, the 1995 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
For circuit and connector terminal identification, see CONNECTOR IDENTIFICATION
in this article. For wiring diagram, see WIRING DIAGRAMS

Turn engine off. Disconnect Powertrain Control Module (PCM) connector. Using an external ohmmeter, check resistance of each wire between Idle Air Control (IAC) motor connector and PCM connector. See PCM TERMINAL IDENTIFICATION table. If resistance for any wire is more than 5 ohms, repair open on appropriate wire. Perform TEST VER-2 . If resistance for all wires is less than 5 ohms, replace PCM. Perform TEST VER-2 .
